To all whom it may concern.

Be it known that we, PRESTON H. ALLEN and HENRY H. ALLEN, citizens of the United States, and residents, respectively, of St. Louis, Missouri, have invented certain new and useful Improvements in Waterproof Containers or Envelops, of which the following is a specification containing a full, clear, and exact-description, reference being had to the accompanying drawings, form-. ing a part hereof.

Our invention relates to certain new and useful Improvements in waterproof containers or envelops and has for its special object the construction of a container or envelop made Outof waterproof material, and so constructed that the mouth of the container or its open endmay be closed and made practically waterproof by the folding of the material out of which the container ismade.

Furthermore our invention has for one of its special objects a fastening device for the container which is firmly united to the container and is proof against the entrance of water to the container, ordust, etc,

In the drawings,

Figure 1 is an inside view of the blank outof which our container is formed. Fig. 2 is a plan view of the container illustrating the closing flap unfolded.

Fig. 3 is a plan view of the container with .the closing flap completely formed and folded.

Fig. 4 is a plan view ofthe container closed.

Fig. 5 is an enlarged sectional view illustrating the material out of which the container is formed, and

Fig. 6 is a section taken on a. line 6- of Fi 4.

Re erring to the drawings, 7 indicates the blank out of which the container or envelop is formed, which is composed of two sheets of flexible fabric or material .8, between which there is a coating or sheet of waterproof material 9. In practice the material out of which our container or envelop is made is two sheets of paper between which there is a coating of waterproof adhesive material. In the making of our container the material out of which it is made is cut and scored, perforated or punched, as illustrated in Fig. 1, wherein IO-indicates the score line on which the material is folded Specification of Letters Patent. 7 Patented ltlar, 4 1919 Application filed May 7, 1918.

and which constitutes the bottom closed end of the container or envelop, that is, when\the portion 11 is folded on the portion 7 along the line 10.

Secured to the portion 11 isa fastener which has an inner disk 12 and an outer disk 13. These disks 12 and 13 are connected together by a metal sleeve 14, and

he flap 17 is then folded along the line 18 and the companion fastener 19 is secured to the flap.

In Fig. 2 we have illustrated the flap 17 unfolded and in Fig. 3 we have shown the flap folded along the folding line 18 and the flap secured in its folded position by means of the fastener 19. The sleeve of the fastener 19 is inserted through-the openings 20 and 21 of the flap which coincide when the flap is folded and which has a thin disk 22 and a slightly heavier disk 23. These disks are united by means of the metal eyelet 24. The fastener 19 is further provided with a fastening cord 25 and a wire fastener 26. When the fastener 19 has been secured to the folded 'flap as described and illustrated in Fig. 3 the container or envelop is then readyfor use and in order to close the container the folded flap as illustrated in Fig. 3 is then folded down on the folding line 26" and upon the container body. When the flap has beenv folded along the line 26 it will be 'understoodthat a portion of the flap will also be folded upon itself along the line 28 thus forming a flap 29 which, when the container has been closed will lie over the edge 28 of the container.

'- In the construction andoperation of clos occupies the position between the folded flap and the body of the container when is effected by the flap 29 which lies adjacentit has been closed, as illustrated in Figs 4 and 6.

It will be seen therefore that the closing edge 28' of the container. Thisfiap 29 etween the container body and the folded flap when the folded flap is secured-in position exerts a slightly yielding or springing pressureover and against the top edge 28 of the container.

The container is closed by means of passand over. the top) ing the cord 25 around the fastener secured to the body of the container in the usual wayi In Fig. 4 we have shown the container closed and sealed by means of a seal 31.

It will be observed from examination of Fig. 2 that the score line 26 is-arranged slightly above the top edge 28 of the container and that the score line 26 and 28 practically coincide when the flap is folded and that when the mouth of the container is closed the flap 29 overlies the top edge 28" of the mouth of the container. The flap 29 as previously stated is carried by the folded flap or that portion of the same that extends below the fastener and it is yieldingly mounted on the folded flap so that when the container is closed, said flap 29 exerts a constant ylelding pressure over and along the top edge 28 of the mouth of the container.

- Having fully described our invention, what we claim is:

1. A container or'envelop constructed of water-proof material and stitched along its sidesgto close the sides of the container, a folded flap projecting beyond the mouth of the container; said folded flap being held in a folded condition by means of a fastener passing through the folds thereof near the folding line, a flap carried by the folded flap and adapted to lie between the folded flap and container and over the edge of the latter when the folded flap has been closed, a fastener secured to the body of the container, and means for connecting said fasteners. v

2. A container orenvelop constructed of water-proof material sides to close the sides of the container, a ,folded flap projecting beyond the mouth of the container, and adapted to be folded along a line slightly removed from the mouth of the container, said folded flap being held in a folded position by means of a fastener passing through the folds thereof near the line on which the folded flap is folded, a flap carried by the free end of the folded flap and adapted to lie over the edge of the container when the folded flap has been closed, a fastener secured to the body of the container, and means for connecting said fasteners.

In testimony whereof, we have signed our names to this specification, in presence of two subscribing witnesses.
